    摘要： A method of manufacturing a semiconductor device includes the formation of a dielectric film on a substrate having an effective device area surrounded by a peripheral area. A resist pattern exposing part of the dielectric film in the peripheral area is formed, and the dielectric film is etched to reduce the thickness of the exposed part. After the resist pattern has been removed, the dielectric film is planarized by chemical-mechanical polishing. Good planarity is achieved because the etching step removes high parts of the dielectric film from the peripheral area. This method of achieving improved planarity is less expensive than conventional methods employing dummy devices.

    摘要： A scroll compressor having an extended life due to the support structure for the orbiting scroll, even when using a chlorine-free substitution refrigerant. The support structure includes an Oldham ring for supporting an orbiting scroll so as to allow the orbiting scroll more orbiting motion without rotating about a fixing scroll. The Oldham ring is formed of a different material from both a fixing member and the orbiting scroll. Hence, if a boundary lubrication state occurs in mutually sliding parts, only sliding between different materials occurs, and mutual adhesion in the portion of the boundary lubrication state is avoided. As a result, the shortening of the life due to the wearing of the support structure of the orbiting scroll is prevented.

    摘要： A scroll compressor includes a fixed scroll and an orbiting scroll which define therebetween a plurality of compression chambers for compressing fluid introduced via a suction port. The orbiting scroll has a base plate and a shaft portion extending from the base plate toward a crankshaft rotatably supported by a support member. A seal member is disposed between the base plate and the support member to define an inner region and an outer region. The inner region surrounds the shaft portion, while the outer region includes therein a rotation preventing member interposed between the base plate of the orbiting scroll and the support member. The inner region communicates with the outer region via an oil-feed passage formed through the orbiting scroll. The oil-feed passage includes therein a restrictor and opens in the neighborhood of an upper sliding portion between the rotation preventing member and the support member. Thus, lubricating oil supplied to the inner region is fed to the neighborhood of the upper sliding portion via the oil-feed passage for lubrication thereof. The lubricating oil collects downward due to the gravity to achieve lubrication of a lower sliding portion between the rotation preventing member and the support member.
